Oerlikon Supradur V1000 description: SUPRADUR V1000 is a thick rutile coated high-efficiency MMA electrode, 160% recovery, the weld microstructure is a hypereutectic stainless chromium hard alloy. Typical applications include hard facing subject to abrasion, e.g. by sand, gravel, coal, soil, clay and related minerals used in ceramics, cement and concrete building materials and mining. Used for hard facing carbon steels and low alloy steels against abrasion by mineral particles and but exhibits limited resistance to impact and shock, the deposit is only machinable by grinding Smooth, regular weld beads are deposited with only minimum penetration. The hardness cracks which typically appear in this weld metal are not detrimental to resistance against mineral abrasion. When welding crack sensitive base materials a buffer layer is required using 307 type MMA electrode. Flat welding position only. Shall be used in DC+ or AC current.
